Background technology
Document FR2954752 discloses a kind of wheel and the brake assembly with gear motor, rotates with drive wheel.Drg comprises the load member for carrying brake actuator, and this load member also carries gear motor and the profile of tooth ring with gear motor fixed engagement.Clutch element makes profile of tooth ring to be optionally connected with wheel, takes turns can be driven by gear motor to make this.Especially, this element is also around the magnetic clutch that actuator load member extends.
Although such device presents many advantages, it may be difficult to be contained in the crowded environment of aircraft wheel sometimes.
Therefore, a kind of device gear motor being connected to aircraft wheel being easy to hold is needed.
Especially, considered and forced profile of tooth ring to rotate together with wheel, and inserted loose pinion connecting device between gear motor and profile of tooth ring.Be arranged on the axle of device to miniature gears idle running, this axle is connected to gear motor thus is driven in rotation.Clutch engagement means is optionally done to enable loose pinion optionally be forced to rotate together with its axle, to provide the connection between profile of tooth ring and gear motor.But loose pinion is also arranged on its axle by antifriction-bearing box (such as cylindrical bearing or needle bearing) usually.If the bearing of loose pinion blocks, gear motor is connected to aircraft wheel, thus runs such risk: gear motor is by wheel drive, and given gear ratio used, gear motor jeopardously fast rotational can be caused.
Summary of the invention
The object of the present invention is to provide a kind of device for the loose pinion of gear motor being connected to aircraft wheel, even if the bearing of loose pinion blocks, this device still can allow wheel to rotate freely.
In order to achieve the above object, the invention provides a kind of device gear motor being connected to aircraft wheel, this device comprises:
Rotatably carry the cover of the axle driven by gear motor, this axle is provided with miniature gears by antifriction-bearing box idle running;

Accompanying drawing explanation
By reading the following description to specific embodiment, the present invention can be understood better by reference to the accompanying drawings, wherein:
Fig. 1 is the longitudinal section of device of the present invention, and wherein miniature gears and axle are disengaged; And
Fig. 2 is the view similar with Fig. 1, and wherein miniature gears closes with being coupling.
Detailed description of the invention
Composition graphs 1, connecting device 1 of the present invention is for providing between gear motor 2 (shown in broken lines in the accompanying drawings) and aircraft wheel by being fixed to the rotary connection of the profile of tooth ring 3 of wheel (equally with dotted line display).
This device comprises cover 4, and axle 5 is installed on wherein, to rotate around rotation axis X.Axle 5 has the end 6 from cover 4 projection, to drive rotation by gear motor 2.Axle 5 carries and is arranged on miniature gears 7 on axle with dallying by cylindrical bearing 8, and cylindrical bearing 8 is made up of side by side two cylindrical bearing 8A and 8B in the present embodiment.
Under normal circumstances, miniature gears 7 rotates freely, thus by the gear motor 2 in rotating with profile of tooth ring 3 and then separate with aircraft wheel.This is for during such as taking off or landing.During these stages, the rotative speed of aircraft wheel may be very high, and if gear motor is connected to wheel, then the motor of gear motor rotates with very high speed, thus there is the risk of damage.
On the contrary, when aircraft moves on the ground with low speed, gear motor needs to be connected to rotate together with wheel, can rotate by drive wheel, makes aircraft move without the need to any help of jet engine by this.For this purpose, this device is provided with and rotates forcing device 50, and for forcing loose pinion 7 to rotate together with its axle 5, this device will be described in more detail below.
When loose pinion 7 rotates freely, importantly avoid blocking cylindrical bearing 8.The event of even now seldom occurs, but not impossible, and if a pause in roller, if or insert foreign material between roller, this may occur.Therefore, in cylindrical bearing 8, produce opposing torque, by this force loose pinion 7 rotate together with axle 5, thus miniature gears by the rotary actuation taken turns rotate.
In order to avoid this situation, and according to the present invention, level and smooth bearing 9 is inserted between cylindrical bearing 8 and axle 5, and this level and smooth bearing is arranged on axle 5 as flush fit, but be installed as and rotate relative to cylindrical bearing 8, thus form second bearing of connecting with cylindrical bearing 8.
Under normal circumstances, loose pinion 7 relies on the roller in cylindrical bearing 8 to enclose and pivots, but not axle drive shaft 5.But if roller blocking, so cylindrical bearing 8 jointly rotates as a unit together with loose pinion 7, this unit relies on level and smooth bearing 9 to enclose and pivots.The friction moment of the friction moment generation more usual than cylindrical bearing 8 that level and smooth bearing 9 produces is slightly large, but still is not enough to axle drive shaft 5.Therefore, even if when cylindrical bearing 8 blocks, axle 5 can not be driven, unless started rotation forcing device.
Whether in order to check cylindrical bearing 8 to block, the cylindrical bearing 8B in this example is equipped with sensor 51, for measure cylindrical bearing 8B two rings between relative rotational.In order to explorer vehicle is static (not having relative velocity to be normal between the ring now detecting cylindrical bearing 8B), device has the sensor 52 of the rotative speed for measuring loose pinion 7.Should observe, the rotative speed that sensor 52 records is identical with the rotative speed of the outer shroud of cylindrical bearing 8B.By relatively carrying out the signal of sensor 51 and 52, be easy to the rotative speed of the inner ring inferring cylindrical bearing 8B, this speed should identical with the rotative speed of axle 5 (this speed be learnt by other means, such as, the means of the rotative speed of one of the rotating element of prototype gear motor 2).If these speed are not mated, be then level and smooth bearing 9 in slippage, thus there is the resistance hindering two rings of cylindrical bearing 8B relative to each other to rotate freely.Therefore the inefficacy detecting cylindrical bearing 8 is easy to.
Rotate forcing device 50 to be described in more detail below.It comprises cliding gear 16, this cliding gear is by axle 5 rotary actuation, and it is axially movable between the engage position shown in the releasing position shown in Fig. 1 and Fig. 2, the inner side slot 17 carried by the bell-shaped section 18 of cliding gear 16 in releasing position is separated with the complementary groove 19 of loose pinion 7, in engage position, the groove of cliding gear 16 and the groove of loose pinion 7 are assisted and are joined, and rotate together with axle 5 to force loose pinion 7.
Cliding gear 16 is moved axially by the screw-nut assembly 20 extended around axle 5.In this example, screw-nut assembly 20 has nut 21, and this nut is mounted to rotate in cover 4 by two ball bearing of main shafts 22, and hollow screw 23, and this hollow screw is threaded connection to assist with nut joins.Nut 21 forms the rotor of motor 24, can see that stator coil extends around nut 21.
Rotating nut 21 causes screw 23 to move axially, and stops screw to rotate, for the sake of clarity, in this example, this rotation inhibiting member is not shown by rotation inhibiting member.Cliding gear 16 is pressed against by roller thrust ring bearing 25 in the end of screw 23.Backspring 26 extends between the bearing 27 be associated with cliding gear 16 and the shoulder 28 of axle 5, to impel cliding gear 16 towards its releasing position, there is effect by this that cliding gear 16 is pressed against roller thrust ring bearing 25, and therefore force cliding gear 16 to move axially together with screw 23.
Therefore, the rotation of motor 24 causes nut 21 rotate and therefore cause screw 23 translation, thus moves axially cliding gear 16.
In this example, the connection between nut 21 and screw 23 is reversible.Magnet stopper 29 comprises the electromagnet 30 that is fixed to cover 4 and forces the armature that rotates together with nut 21, and this magnet stopper can optionally stop nut 21 to rotate, thus cliding gear 16 is axially fixed in engage position.For reasons of safety, magnet stopper 29 only stops nut 21 to move when drg 29 is energized.When drg 29 no power, cliding gear 16 is from returning to releasing position under the driving of spring 26.
Indicating device 32 is fixed to screw 23, to make one end of indicating device mobile in the longitudinal slot 33 of cover 4, in this groove likely sensor installation to detect joint and the releasing position of cliding gear 16, or positively, if necessary, to detect any midway location between these two positions.
In particular aspects of the present invention, anchor fitting is equipped with synchronous device in a conventional manner, and it comprises:
There is the baulk ring 10 in interior tapered face 11, be applicable to being assisted by the outside conical suface 12 of friction force and miniature gears 7 joining; And
Hub 13, is connected by groove and forces hub 13 to rotate together with axle 5, and comprise and assist the grooved outer of joining with the groove of cliding gear 16, to drive it to rotate.At least some external concavity in hub 13 is taken by key 14, and these keys are promoted radially outwardly by spring coil 15.
The operation of this synchronous device is known, and does not specifically describe in this article.Recall following content just enough: when cliding gear 16 is pushed to loose pinion 7, the conical suface friction of baulk ring 10 is against the outside conical suface of the complementation of miniature gears 7.So friction force makes axle 5 rotate, until its rotative speed is consistent with the rotative speed of the loose pinion 7 that the revolving wheel by aircraft drives by profile of tooth ring 3.Baulk ring 10 and loose pinion 7 comprise identity device, for stopping these two elements angled at axial location, align with the complimentary recess on the groove 19 of the groove 18 with loose pinion 7 that make cliding gear 16.Cliding gear 16 can advance until it engages with loose pinion 7.Loose pinion 7 positively connects to rotate together with axle 5.
The invention is not restricted to foregoing description, but cover any variations in the scope that is defined by the claims.Although antifriction-bearing box described herein has the cylindrical bearing of roller as rolling element, the antifriction-bearing box of other type arbitrarily also can be adopted, such as needle bearing.
